Manufacturing process of swimming pools, ponds and other similar areas of water

Abstract

This method includes the steps consisting in creating an excavation; installing a watertight membrane ( 11 ) over the entire excavation and over the area ( 5 ) intended to receive the coping; installing grids ( 21 ) along the lateral walls of the excavation, at a specific distance from the watertight membrane ( 11 ); connecting these grids ( 21 ) together pouring concrete ( 30 ) into the excavation and immobilizing the grids ( 21 ) with respect to the excavation; holding the upper portion of the grids ( 21 ) in relation to the ground filling the space between the grids ( 21 ) and the watertight membrane ( 11 ) with a decorative filling material, in particular pebbles ( 39 ); and building the coping so as to permanently immobilize the grids ( 21 ).

1 - Method for constructing a swimming pool, a pond or another similar body of water ( 1 ), which comprises:
 creating an excavation having a shape corresponding to that of the body of water ( 1 ) to be obtained;   installing a watertight membrane ( 11 ) over the entire excavation and over the area ( 5 ) intended to receive the coping, over a width at least equal to that of this coping;   installing, if need be, equipment that must be included at the lower portion of the body of water ( 1 ), in particular when the body of water ( 1 ) includes an integrated filtration system, the pipes ( 15 ,  16 ,  17 ), outlet covers and other elements included in this filtration system;   installing grids ( 21 ) along the lateral walls of the excavation, these grids ( 21 ) being provided with spacers ( 21   b ) making it possible to hold them at a specific distance from the watertight membrane ( 11 );   connecting these grids ( 21 ) together   pouring concrete ( 30 ) into the bottom of the excavation so as to form a slab constituting the bottom of the body of water ( 1 ) being constructed and immobilizing the grids ( 21 ) with respect to the excavation;   holding the upper portion of the grids ( 21 ) in relation to the ground;   when appropriate, positioning equipment on said grids ( 21 ) that the body of water ( 1 ) must include, such as other elements of the filtration system, in particular water return fittings ( 37 ), and/or floodlights ( 38 );   filling the space between the grids ( 21 ) and the watertight membrane ( 11 ) with a decorative filling material, in particular pebbles ( 39 ), up to the level of the area ( 5 ) intended to receive the coping; and   building the coping so as to permanently immobilize the grids ( 21 ).   
   
   
       2 - Method according to  claim 1 , after producing the excavation and before installing the watertight membrane ( 11 ), the steps of:
 laying a peripheral trench ( 3 ) at the bottom of the excavation, at the base of the lateral walls thereof, and   inserting the lower portions of said grids ( 21 ) into this trench.   
   
   
       3 - Method according to  claim 2 , further comprising installing inside said trench ( 3 ) equipment that must be included at the lower portion of the body of water ( 1 ), in particular when the body of water ( 1 ) includes an integrated filtration system, the pipes ( 15 ,  16 ,  17 ), outlet covers and other elements included in this filtration system. 
   
   
       4 - Method according to anyone  claim 1 , further comprising, prior to installing the watertight membrane ( 11 ), in installing a geotextile felt ( 10 ) over the entire surface intended to be covered by this membrane ( 11 ). 
   
   
       5 - Method according to  claim 1 , characterized in that each of the grids ( 21 ) used is preferably L-shaped, that is to say that each grid includes both a main flat portion running parallel to the lateral wall of the excavation, and a lateral portion arranged substantially at a right angle in relation to the main portion. 
   
   
       6 - Method according to  claim 1 , characterized in that it the upper hold on the grids ( 21 ) is produced by bars ( 31 ) anchored to the ground and by double-hook link rods ( 32 ) which, on the one hand, hook onto the grids ( 21 ) and, on the other hand, onto said bars ( 31 ). 
   
   
       7 - Method according to  claim 6 , characterized in that said bars ( 31 ) are situated in a space intended to be filled with concrete ( 40 ) in order to form a layer for receiving the coping, and the construction of the coping includes the step consisting in pouring concrete ( 40 ) into this space, over the decorative filling material ( 39 ) and over said bars ( 31 ) and link rods ( 32 ), so as to form said layer for receiving the coping. 
   
   
       8 - Method according to  claim 7 , characterized in that a geotextile felt ( 10 ) can be put in place over the watertight membrane ( 11 ) before pouring the concrete ( 40 ) intended to form said layer for receiving the coping. 
   
   
       9 - Method according to  claim 8 , further comprising:
 anchoring the bars ( 31 ) into the ground using fastening elements ( 35 ) inserted into the ground beyond the watertight membrane ( 11 );   removing these fastening elements ( 35 ) after pouring the concrete ( 40 ) intended to form said layer for the coping, and   making the body of water ( 1 ) watertight in relation to the ground by bringing said watertight membrane ( 11 ) up and over the coping, with the possible installation of overflow pipe connections ( 42 ).   
   
   
       10 - Method according to  claim 1 , further comprising:
 producing at least one secondary vertical excavation ( 4 ), opening out into the main excavation;   installing at least one pipe ( 16 ) opening out into the lower portion of this secondary vertical excavation ( 4 ), before pouring the concrete intended to form the bottom of the body of water ( 1 ) to be obtained, and   installing, in this secondary vertical excavation ( 4 ), a concrete pipe ( 20 ) including an upper notch the height of which is such that said notch is situated at the surface level of the water after construction of the body of water ( 1 ), this concrete pipe ( 20 ) being intended to receive a water suction element connected to said pipe ( 16 ), and said notch being intended to receive a weir, the assembly constituting a surface cleaner, commonly named a “skimmer”.
